    Cold weather, reduces range.
    Or you are driving it faster, also reduces range! :)

    The cold weather will affect it. Are you always charging it fully ? Should have a look at your driving style. There's an app called CanZE you use with a OBD2 that will tell you the state of the battery but that shouldn't be an issue.

    Ok, i will try to download it. Not always, but mainly yes fully, just i charge it at town chargers, maybe that wrong, just because i dont have home charger, just granny charger for incase, but used it just once.

    Had the Renault fluenze ze same issue. During very warm summer weather get 120-140km on charge
    During winter cold weather 60-80km on charge.
    Had for 2 years lovely car range wasn't good enough for my needs.

    You'll be using the heat more in the colder months and having window demister on etc.

    Yes i understand if its goes down faster, but it charge fully 100% just 44miles

    Surely this range drop can’t be acceptable??? The OP must have a car with a problem as that limited range is really poor? We could have this same level of cold weather across 5 months of a given year

    44 miles seems really bad. My i3 has gone down to 60ish miles on the coldest days recently but i'm driving 100kph on main roads.

    Do you charge all night? What temperature is the heating set at? Do you precondition.

    Cold should only drop the voltage by 20%, I recently had the dealer do a BMS, ( battery management system) software update, problem fixed. Although just because the display reads more miles, who knows if it did anything to the car?

    How long do you charge for and is it fast chargers or slow chargers on the street.

    The batteries may not be hooked up long enough to do a balance.

    Is the car left for long periods at full charge?

    If you could get a home charger it may be better as you can set the time you will be using the car and it won't start charge till it knows how long it needs to be full for the time you need it.

    It would also be good for the morning heat up and that as it won't drain the battery.

    It unlocks some of the headroom so you do have some more electrons available.

    But does it involve Quantum Entanglement?

    There is a software update that fixes this problem, although I had to push the dealer to do it.
    Renault will only pay the dealer back for somethings. Last winter I was only seeing 60 miles on a full charge, today, warm day I am seeing 100,having had the software.
    I couldn't say, like a few things on the screen, if this actually makes any difference to the battery state?
